Europe may be getting cold but explosions a million times hotter than the sun have been going off under France and Switzerland.
The reason is that the Large Hadron Collider (LHC) has successfully switched over from firing protons into each other and is using lead-ions instead. The first collisions have been successfully achieved, creating explosions of incredible temperatures that seek to recreate the conditions shortly after the Big Bang.
"We are thrilled with the achievement!" said Dr David Evans from the University of Birmingham.
"The collisions generated mini Big Bangs and the highest temperatures and densities ever achieved in an experiment."
The power of these impacts is that much greater than that for simple protons, since lead-ions contain 82 times the reactive mass. The terabytes of data from each impact are stored on one of the world's largest tape storage arrays for future study.
The impacts are not only good science, they demonstrate how far the LHC has come from it's unfortunate start. The shift from firing protons to lead-ions was completed in just four days and is already working well.
"The speed of the transition to lead ions is a sign of the maturity of the LHC," said CERN director General Rolf Heuer.
"The machine is running like clockwork after just a few months of routine operation."
So far there have been no signs of the time travellers or black holes that some posited once the LHC was operational. However, if may give CERN scientist AlpineKat more fuel for a musical career that started with the LHC Rap - which has now been viewed by more than six million people.
